爱上你就是我最大的幸福用英语怎么说

Falling in love with you is my greatest happiness.
我觉得这样说通俗易懂些！最好表达幸福时不要用biggest,因为爱是抽象的，或用ultimate,extreme都行！

Finding you is my biggest happiness.
or
Loving you is my biggest happiness.

I love you is the greatest happiness

It's my biggest happiness that fall in love with you

I love you is the greatest happiness
